- To ensure efficient design and validate a product reliability, it is essential to link the sample targets to the real intend use. SMS (Smart Mobile Solutions) is a tool which allows fast simulations of real-world routes with vehicles, drivers and driving conditions. Real-world routes can be generated from Google Maps and a large number of route lengths and types can be built up with low effort. This allows an extensive and varied usage space to be generated quickly and efficiently. One fundamental restriction of such a tool is that bias can be introduced in terms of the expected driver behavior and selection of routes. Variables such as maximum acceleration, maximum deceleration and maximum speed are used to characterize the simulated driver types. Without big data analysis it is possible that the usage space will be distorted by the expectations of a limited sample of people and so the fundamental link to reliability will be inaccurate. Through analysis of many real driven profiles with instrumented vehicles, the typical characteristic and variations of drivers and routes can be determined. In addition, through application of damage models to compare the damages generated in real and simulated driving, the sensitivity to different driver characteristics can be explored in terms of their impact on the key variables of component design and reliability.
